Application filed December 1, 1920.

To all whom it may concern:

Be it known that we, CHARLES and (humans B. Monnrsrr, citizens of the United States, residing in Indianapolis, Indiana, and Philadelphia, Pennsylvania, have invented certain Improvements in an Automatic Oiler for Chains, of which the following is a specification.

One object of our invention is to provide a simple and effective device for oiling drive chains.

A further object/of the invention is to pro vide' means whereby the oil can be thrown against an overhead. drip plate it will drip onto a chain.

These objects we attain in the following being had to the accomin which Fig. 1 is aside view of our improved oiling device for drive chains;

Fig. 2 is a longitudinal sectional view;

Fig. '3 is a transverse sectional view on the. line 3-3, Fig. 2; A

Fig. 4 is a transverse sectional view on the line 4.4, Fig. 2; and

Fig. 5 is a view of a Refernng to the drawings,

from which modification.

1 is the driven Mounted on the driven shaft is a sprocket wheel 3 and mounted on the driving shaft is a sprocket wheel 4. 5 indicates a drive chain by which the shaft 1 is driven from the shaft 2. The two sprocket wheels are located within a casbase section 6 having a comparatively deep flange 7 and an interme- .diate section 8, which is located withing the base section, as shown. Mounted on the inter: mediate section 1s a cover sectlon rests on lugs 10secured to, or formed on,

the intermediate'seetion. In the present instance the lugs are made of angle metal and are welded to the intermediate section. Se-

- cured to theshaft 1, or to the sprocket that by the disk 11,

wheel.3, is a disk 11, which is of greater diameter than the sprocket wheel 3' so that the lower edge of the disk will extend into the oil in the bottom of the'casing, as shown in Fig. 2. -Mounted on the under side of the cover section 9 is a drip plate 12, which is pressed into such a shape that the oil, is splashed up against theudrip plate will travel dinal center line of the chain so that the oil Specification of Letters Patent.

will drip onto the chain at this point.' In the present instance, the -cover slightly beveled from side to side and from end to end so that the lowest part of the plate is at the point so.

In ordinary practice, theshafts 1 and 2 may extend through'openings in the side of the box, but where it is necessary to adjust a shaft, such as the'fs'haft 2, to take up for wear, aslot 13 is? formed in the intermediate section and a recess 16 is formed in the base section. A sealing provided, which has a hole 15 therein of substantially the same diameter as the shaft 2 so as to receive the shaft. This plate is duplicated on the opposite side, if the shaft extends through the casing, but, if the shaft merely projects into the casing, as in Fig. 3, then a separate plate 14 is placed be twee the intermediate section and the base to close he opening.

In order to prevent oil the shaft 1 at the openings, provided, which is secured to each side of the intermediate section directly abox' e shaft, as shown in Fi s. 1 and it.

18 is a drip pipe for removing the oil from the bottom of the casing, when necessary.

Fig. 5 illustrates a modification, in: which the drip plate 12 is formed as an integral part cover dripping onto being pressed to form the dripplate,

, The operation of our improved oiling detravels down'the drip plate to the lowest point, which is directly above the chain. When a sufficient amount of oil accumulates at this point, it drops from the drip plate onto the chain, lubricating the chain. this operation is repeated,'the' chain becomes thoroughly lubricated and any surplus oil will drip from the chain onto the bottom of 'the casing.

It will be ment, the lower run of the chain preferably Patented June e. was.

We claim:

1. The combination in means for lubricat- .ing a drive chain. of a casing; two sprocket shafts extending: through a Wall of the casing; a sprocket wheel on each shaft; a drive chain extending from one sprocket Wheel to the other, the casing being of such depth as to form an oil chamber in the bottom thereof. the oil in the chamber being normally below the chain; a disk on one oi said shafts. said disk being oi such diameter as to extend into the oil; a coi er for the casing; and a drip plate under the cover depressed at the center above the chain so that oil, carried by the disk, will be splashed onto the drip plate and will travel to the loves point and will dri h onto the e chain.
